"To all whom it may concern! Be it known that I, JAMES J. KELLY, a (iii-f This invention relates to machines for' dressing and finishing surfaces of floors by "means of revoluble tool-holding devices carried by a frame provided with carrying- 4 wheels, which frame is moved and guided by means of' a'handle' having'on its upper -por- ""ISfJiOH means for sup iying'andjtransmitting "power to the rev'olu le floor-dressin devices button D is ivoted on the face of socket O forsecurely olding the'two halves of the frame togetherjwhen the revolublc devices are in place for operation. Coineidinghalf 6o bearings z znre provided in the lowen and upper edges, respectively, of frame portion a am a, which'rcceive the journals w of thecarrying-wheels W,-as-shown in'Figs; 1, 2-

I and 5. Notchcs e a re also provided in upper 65 edge of frame portion a to receive the late res which secure the rcvolnblc floor-dressing devices in place in frame A.

The handle F, Figs. 1, 2, and 4, is prefer-y ably made of wood and secured to thefrarne by means of the socket l), which receives thef lower ends-of same and issecurely heldin carried :by the frame below, whic device place by means of boltsff, as shown in Figs.

The upper end of handleF,.F1g.- scrapers, brushes, 01;, as shown in this appliterminatesin-a knob K, of horn or-othersuitcation, asand-papenng disk, which aroused, able form, for "conveniently. propelling and respectively, for the performance'of their individual functions in their order, still using -"the same frame and'actuatin devices for o'pcrating thesame for giving t dressing to a'fioor-surface. T The ob ects and'purposes of this invention will be clearly understood from'the followin description whentaken in connection wit theaccompanyingI drawings, in' 1one' sheet,

forminga part of t s specificationfin which- Figure 1 is a side elevation of this machine .with'part insection; Fi 2 is a'glan vfiewof the frame, having secnr in itt f'e revoluble floor-dressing device, and shows part of the frarneof the machine; Fig. 3 is a transverse section taken at line 1, Fi 1', and shows the revoluble floordressin BVIOB and its adjuncts and "the means or securing said de vice in the frame. Fig. 4 is a face view of the upper ortion' of the handle, showing the means or supglying and transmitting gower to the 'revolu le device in the frame slow and the means for adjusting and securing the same. Fig 5 is a longitudinal section at line 2 in Fig. 2 with the revoluble floor-dressing mechanism removed. h

The s'ame letters of reference refer to the same parts throughout the several views.

In the drawings, A, Figs. 1, 2, 3, is a'suitable travelin frame for supporting the revo luble floor ressing' "parts of the machine The frame A'is composed of the upper an lower halvesayaflwithhinges B connecting them at their forward ends. The rear cndot' e desiredfinish 55 half'portion a has secured to it the handlesocket C bymeans ofbolts c c, and a leverprovided with a cranleh. These drive essmg devicessecured in' framo'A by means of drive-chain L, as shown-in Fig. .1. and the power is imparted by means of crank it}, to one of the (inve-sprockets-H, An eccentric I, provided withhand lever 1?, is applied to the handle F, Fi s. 1 an'dA, and 9 5 bearm against the under side of bracket G is used to take the unnecessary slack on? of the drive-chain L., Its pivot, is the bolt 1'', which passes through the slot J in handle F, and is secured b a nut a ainst a wear-plate on the underside of handle F; This eeeentrio also acts as an auxiliary brace to. thebclts I I for retainin the bracket G in place when poweris applie to the dri've chain' Th floor-dressing mechanism which I use in this inventionfepnsists of the horizontallyolving disk M,shown to carry a sandpa 'ng-surface m, Fl 's. l, 2, and 3, although.

lb plates may be applied a iiprockets transmit motion to the revolubie.

oerdr 9s re pe other interchangeab to the diskM, adapted to carry scrapers, brushes, or other iioor-iinishin tools. (Not shown.) The tool-carrying isk M is proward one another, which, as shown in Fi s. 2,

vided with a vertical shaft N, having on its upper end the miter-gear n, which worksin bearing a in yoke P. Miter gears n n impart motion to miter-gear by means of sprocket Q, through short. shafts g, which are revolved b drive-chain L, actuated by dri've. sprockets as shown in Fig. 1. A ooveis made on the u per end of vertical shaft N, which is entered by the point-screw n in hub of horizontal miter-gear n, (shown in Fig. 3,) which allows the disk M to have movement verticall and the shaft is 'made elastic by means 0 the spiral tension-spring 0. (Shown in same figure.) The yoke P, in shape and proportions as shown in Figs. 1, 2, 3, and.5, serves to sup ort the shaft N in a vertical position and as a bearing a, and each limb is provided with feet 1) which rest on the en s of transverse mem er R.

- S is a clip having its free ends turned into- 3, and 5, serves toseeurely bind the o e P and transverse piece R to ether an allow passage for the holding-late es T. The hold- -latches T pass betweentransverse member R and the lower part of clip S, projecting beyond same a distance equal tothe thlckness of sides of frame A and are secured by set-bolts s. Bolts 1' pass through the clip '8, feet of yoke 'P, and transverse member R, secure y holdingi them together, asshown in Figs. 1, 2, 3, an 5. Short transverse shafts q, which are in alinement with drive-sprockts H, havin on their outer'endssprockets Q, are p through -lugs a on up er halfframe portion a, then through the imbs of yoke P Figs 1, 2, and 3, into the hubs of the vertical miter-gears n, terminating at the vertical shaft N, and boththe horizontal and vertical shafts have bearing in the cross-form sleeve X. (Shown in Fig. 3.) The mitergears n are secured to the shaft 9 by screws or pins, as shown in same figure.

The manner in which the machine is set up is as follows: The hinged frame A, provided with handle F, secured to said frame, as described, is opened by throwing over the latch D free of the upper half a and swin ing the half-frame member upward and orward. Then the revolving floor-dressing device last abovedescribed is inserted in place, with the holding-latches T resting in notches e, Fi 1. The carrying-wheels W are placed with t eir journals w resting in half-bearings w, Fig{ 2. The n per half-framed is thenswung back. into p ace and the button-lever thrown toa vertical osition, as shown in Figs. 1 and 2, securely ocks the floor-'dressirig'parts to the carrying-frame. Then the bolts I, Figs. 1 and 4, as'we'll as the pivot-bolt l, areloosened by turning the nut and thumb-nutsfof same, and the bracket 'l'rioved downward enough to allowthe driveiliain L to be passed over sprocket Q of are flbor-dressingmechanism and the drive i pf o cket H. The bracket G is then slid upward approximately to its proper place and then permanentl adjusted by turning the lever eccentric l. T 1e thumbnuts 1', i are then tightened and the machine is read for operation. It is to be understood t at previous to'its insertion in the carrying-frame the disk M'has secure to its under surface either the applied sandpapering device, as shown in the drawings, or the other interchangeable floor dressing device, as scrapers or brushes before mentioned, but not shown.

Although the drawings show a crank-h, provided on one of the drive-sprockets H, for

adjusting the working parts of the machine by manual power, yet the crank may be dispensed with and any other suitable power, as of electric motor, compressed-air, or vrfor engine, be used to the same purpose. 'ihe.

frame A, provided with its handle and adjuncts for supplying power, is adapted to readily receive or release the operating parts of the revoluble floor-dressinggdevice, which ma be fitted with such interchangeable surfacing-tools as the nature of the work may require in dressing or surfacing a floor, and this machine, complete in itself, obviates the use of several separate machines forwork of this nature Having described my invention, what I claim, and desire to secure by Letters-Pa tent, is-
